Do Data Removal Services Really Work?

You may wonder if Data Removal services really work. The article below examines data-recoverability concerns, the security of overwriting, and the cost of de-identification. If you’re worried about privacy, consider a data removal service. Learn how it works. You might not be aware that your data has been shared.

Security of overwriting

Multiple passes of the disk blocks are required to ensure security of overwriting during data removal. This requires a cryptographically strong random generator. It also prevents the opponent’s ability to predict which pass was before. Overwriting data with two passes is a strong first step, but it is not fool-proof. An attacker can still read data by subtraction from previously written data. Fortunately, many programs use the 35-pass overwrite technique.

Recoverability of de-identified data

While the current de-identification strategies may have high recall and precision rates there are many flaws. Some PHI is more sensitive than others and cannot be de-identified. In addition, current systems and algorithms are not designed to deal with diverse PHI, including regional nomenclature. Regardless of the limitations of de-identification, these techniques will still require careful data handling and ongoing testing.

Cost of overwriting

Overwriting data has a number of benefits, including the ability to destroy information without damaging the storage equipment. While the process isn’t as secure as destroying the storage equipment, the data is still readable. Furthermore, the process can be traced back to the storage device.

Overwriting reliability

One of the most common issues with storing personal data is the risk of compromising this information. These data include bank account information and healthcare information. Even the smallest mistakes can lead to the data being misused or exposed. Overwriting can help to prevent these risks. However, data recovery must be done correctly. There are ways to make sure that overwriting doesn’t happen accidentally. Additionally, the less likely it will be that sensitive data is discovered, the more drives perform overwriting.
